Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0019] like Figures 1 to 3 As shown, a foldable bag in this embodiment includes a foldable bag 1, a connecting base plate 2, a supporting base plate 3, and several wheels 4.
[0020] The foldable bag 1 includes a bag body 11, a top cover 12, and a handle 13.
[0021] Both the bag body 11 and the top cover 12 are made of a foldable fabric with a certain degree of support, such as Oxford cloth, non-woven fabric, etc. The bag body 11 has a cavity 14 with an open top 141 inside, and the bag body 11 in this embodiment can be rectangular.
[0022] The top cover 12 is used to movably close the top opening 141 of the bag body 11. Specifically, one side of the top cover 12 can be rotatably connected to one side of the top opening 141 of the bag body 11, and the remaining three sides of the top cover 12 are detachably connected to the other three sides of the top opening 141 of the bag body 11 via zippers 15, so as to facilitate the storage of contents in the cavity 14 by opening the top cover 12 or to close the opening 141 of the bag body 11 by closing the top cover 12.
[0023] In this embodiment, the top surface of the cover 12 may also be provided with an upper bag 121, and an upper pocket may be formed between the upper bag 121 and the cover 12.
[0024] The handle 13 is located on the side of the bag body 11 and can be made of soft strap, which makes it convenient to lift the bag body 11 for movement during use and also convenient to fold and store. A flexible tube 17 can also be fitted onto the soft strap of the handle 13 to improve the feel of use.
[0025] The supporting base plate 3 is a rigid plate, and the connecting base plate 2 can also be a rigid plate. The connecting base plate 2 and the supporting base plate 3 are respectively set on the upper and lower sides of the bottom surface of the bag body 11. The connecting base plate 2 is located in the cavity 14, and the supporting base plate 3 is located below the bag body 11. Each walking wheel 4 is evenly distributed and installed below the supporting base plate 3.

The connecting screw 41 passes through the top of the connecting base plate 2 and is locked with a connecting nut 42.
[0026] Therefore, by using the connection screw 41 and the connection nut 42 of the walking wheel 4, the bottom surface of the folding bag 1 can be directly clamped between the connecting base plate 2 and the supporting base plate 3, and the supporting base plate 3 and the connecting base plate 2 can be used to support the folding bag 1, which facilitates the movement of the walking wheel 4.
[0027] When the top cover 12 of the folding bag 1 in this embodiment is opened, items can be stored in the cavity 14 through the opening 141. It can be used when moving or camping outdoors. The bottom plate support 3 provides support, the folding bag 1 provides storage, and the wheels 4 make it easy to move and use. When not in use, the folding bag 1 can be compressed and folded as a whole, which can greatly reduce the product volume, make it easy to store, save space, and can be easily put into the trunk of a vehicle or other places without taking up extra space.
[0028] This embodiment has a simple structure and is easy to manufacture and assemble. It only requires setting corresponding clearance holes 5 on the supporting base plate 3, the bottom surface 110 of the bag body and the connecting base plate 2 respectively, so that the connecting screw 41 can pass through, and the assembly and fixation of the folding bag 1, the connecting base plate 2, the supporting base plate 3 and the walking wheel 4 can be quickly realized.
[0029] In this embodiment, a walking wheel 4 is installed at each of the four corners of the bottom surface 110 of the bag. The walking wheel 4 can be a universal wheel structure to facilitate the user to use the handle 13 to drive the folded bag 1 to move.
[0030] See Figure 4 In this embodiment, the four edges of the side of the bag body 11 of the folded bag 1 are respectively sewn with stitches 6 to form reinforcing edges 7, which can improve the overall rigidity of the side of the bag body 11 and prevent the bag body 11 from being too soft and collapsing, thus affecting its use.
[0031] The bag body 11 in this embodiment may include a front bag body 111 and a rear bag body 112 that are sewn together. The front bag body 111 includes a front side 1111, a front bottom surface, a front left surface 1113, and a front right surface 1114. The rear bag body 112 includes a rear side 1121, a rear bottom surface 1122, a rear left surface 1123, and a rear right surface 1124. The front bottom surface and the rear bottom surface 1122 are sewn together, the front left surface 1113 and the rear left surface 1123 are sewn together, and the front right surface 1114 and the rear right surface 1124 are sewn together to form the bag body 11 structure with an open top surface 141 of the cavity 14. Moreover, the sewn position can form a sewn reinforcement edge 8, which can further increase the rigidity of the middle part of the left and right sides of the bag body 11.
[0032] In this embodiment, the supporting base plate 3 may include an upper plate 31, a middle plate 32 and a lower plate 33. The upper plate 31 and the middle plate 32 may be flat plate structures, and the middle plate 32 may be corrugated plate structures, which can increase the structural strength of the supporting base plate 3.
[0033] The upper plate 31, middle plate 32 and lower plate 33 of the supporting base plate 3 can all be made of lightweight aluminum, lightweight alloy and other metal materials.
[0034] In this embodiment, both the bag body 11 and the top cover 12 can be made of multi-layer materials.
